One man was killed and at least nine other people have been wounded in shootings in Chicago since Saturday morning, including an off duty Oak Park police officer, police said.

Most recently in the city's Englewood neighborhood at 10:30 a.m., a 23-year-old man was driving south in the 6700 block of South Bishop Street when a gray minivan drove past him and a gunman inside opened fire and hit him multiple times in the torso, said Officer Jose Estrada, a spokesman for the Chicago Police Department.

The gunfire also hit the right thigh of a 24-year-old female passenger.

The wounded motorist was able to drive to Holy Cross Hospital, but he was transferred to Mount Sinai Hospital, where he was listed in critical condition, Estrada said.

The woman was in good condition at Holy Cross Hospital.

No one is in custody for the Bishop Street shooting, Estrada said.

Earlier, about 6:30 a.m. in the city’s Chicago Lawn neighborhood on the Southwest Side, a 28-year-old man and a 23-year-old woman were shot in the 5900 block of South Kedzie Avenue, said Officer Stacey Cooper, a spokeswoman for the Chicago Police Department. Cooper was citing preliminary information.

They were being treated at Holy Cross, but further details were not available.

At 5:13 a.m., a 58-year-old off-duty Oak Park officer was shot during an armed robbery on the Far South Side.

A family member said the officer was leaving for work when he was approached by two males armed with a gun in the alleyway behind his home in the 300 block of West 103rd Place.

There was an exchange of gunfire -- five or six shots -- and the officer was hit in his arm and leg, said the officer's grandson, Semaj Patterson, 19.

Oak Park police said the officer, a 25-year veteran, was in "stable" condition after being taken to Advocate Christ Medical Center in Oak Lawn, said Oak Park police and family.

Chicago police are questioning two people, but no charges have been filed.

The fatal shooting happened early Sunday morning in the Marquette Park neighborhood on the Southwest Side.

About 12:40 a.m., a 26-year-old man was standing on the sidewalk in the 3100 block of West 64th Street when two gunman approached him on foot and shot him in the chest, police said. The man, Nyerere Lloyd of the 6600 block of South Troy Avenue, was pronounced dead on the scene.

Following the shooting, police taped off a stretch of 64th Street between Kedzie Avenue and Troy Street. The man's body lay covered by a blue sheet on the sidewalk as detectives worked. A small group of people who knew the man stood behind the yellow police tape on the west end of the crime scene near 64th Street and Kedzie Avenue. A woman crouched weeping near the corner as a man hugged her and tried to console her.

On the east side of the crime scene, a woman and her niece watched as detectives investigated near the man's body.

The woman, who asked not to be named because she lives in the neighborhood, said she heard arguing and looked to see a gunman fire a single shot.

"I saw the fire from the gun, and I saw him fall in slow motion," she said, adding she then called 911. "It just happened so quick."

"It's getting ridiculous," the woman said of violence in the Marquette Park neighborhood. "It's just sad. ... It's only May."

Jose Martinez had walked from his home to see what had happened. Martinez, who has lived on 64th Street for about five years, said the neighborhood's gun violence seems to stay on the east side of Kedzie Avenue.

"I don't know what it is. It's like the dividing line," said Martinez, who lives west of Kedzie. "Every two or three months, it's 'boom, boom, boom.'"

Police said no one was in custody in the killing.

Hours earlier, a 27-year-old man was wounded in a drive-by shooting in West Englewood.

The 27-year-old was driving a sedan northbound about 10:15 p.m. in the 6400 block of South Wood Street when someone inside a dark-colored van fired shots while turning on a nearby corner, police said.

The man was hit in his upper back and left arm. He was taken to Stroger Hospital, where his condition stabilized, police said. No one was in custody as of late Saturday.

A 20-year-old was accidentally shot by a friend inside a home about two blocks away, police said.

The 20-year-old man was shot in his left hip by a friend who was playing with a gun in the home in the 6200 block of South Wood Street. The shooting happened about 10 p.m.

The man was also taken to Stroger Hospital, where his condition stabilized. Police said late Saturday someone was in custody for the shooting.

A 19-year-old man was in fair condition after being shot in the Uptown neighborhood Saturday evening, according to police spokeswoman Officer Bari Lemmon.

The man was shot in the thigh about 5:20 p.m. in the 800 block of West Agatite Avenue, Lemmon said. Someone took him to nearby Weiss Memorial Hospital, Lemmon said, but he's being transferred to Northwestern Memorial Hospital.
